• SNR LTC2378-20 LTC2380-24

    Hello everyone,

    I was trying to compare the SNR of these 2 ADCs: LTC2378-20 and LTC2380-24. Looking at the SNR vs frequency plot (pag6 LTC2378-20), pag 7 LTC2380-24) we can see that the SNR 

    becomes lower for higher frequencies for both ADCs. Initially…

  • LTC2380-24 SNR SINAD

    Hi ADI,

    According to LTC2380-24 datasheet, SNR,SINAD dropped according to the input frequency. But the chart only shows 0 to 200KHz. Do you have more information about higher frequency?

    Thanks!

    Cheers

  • RE: LTC2380-24 Multiplexing

    Hi Vitor,

    To deal with the bipolar signal, I would suggest using a fully differential amplifier such as the ADA4945-1. The amplifier can be used to translate the bipolar signal from your preamp to the signal level required by the ADC. Additionally the…

  • Selecting a Multiplexer for LTC2380-24

    Hello!

    I need help selecting a MUX for using with LTC2380. At least 2 differential bipolar channels are required. Signal BW is about 100KHz. I've made a design with the help of Analog Precision ADC tool:

  • Modeling the LTC2380-24 reference pin currents

    Dear all,

    I have a lab measurement application that requires fast sampling with high DC accuracy. For the ADC we have selected the LTC2380-24 with a 5 V reference input voltage (derived from an LTZ1000 reference). The input voltages will be sampled in…

  • RE: LTC2380-24 DC Measurements with DC2289A

    If the input voltage is zero, the noise of the reference should not matter as much.

    1) The common mode voltage of the LTC2380-24 must be held at VREF/2 +/-100mV. With the two inputs tied together, the input voltage must be held at 2.5V +/-100mV when using…

  • Ask questions about LTC2380-24 ADC Driver design

    Hi,

    Here is an example of LTC2380-24 ADC Driver design, I will have some questions to ask.

    a. Based on LTC6363 datasheet, the settling time is 720ns(to 4ppm), on the other hand, the RC time constant is τ=R6*C6=60.4*33=1993.2nS. But

    the acquisition…

    Hi

    In LTC2380-24 datasheet, 

    Which setting is used in LTC2380? (How ns is acquisition time?)

    With Precision ADC Driver Tool,

    ・ADC Driver is LTC6363(short circuit current is near LTC6362).

  • How to synchronize two LTC2380-24 boards?

    Hi,

    How two ADC LTC2380-24 ADCs can be synchronized so that the sampled data from the ADCs are phase aligned ?

    Thanks a lot in advance for your help !

  • DC2289A-A demo board to test the LTC2380-24 ADC

    Hi,
    I've bought a DC2289A-A demo board to test the LTC2380-24 ADC.

    I'd like to be able to provide the board with an external clock, but at the same time being able to control it from the Lindiuno associated board.

    Is this possible?

    Best,
